TRACTOR BRAKE AND BUMPER ATTACHMEN T.

Application filed June 25, 1923. Serial No. 647,708.

The invention relates to tractors and re-- fers particularly to tractor brake and bumper attachments. The invention has among its objects the provision of a common sup port for the brake actuating mechanism and a bumper; the provision of a bumper in advance of the tractor and connected to a support upon the rear axle by means of which any stress upon the bumper is transmitted directly to the rear axle and readily taken care of; the provision of a support upon the rear axle housing comprising a split bushing having inwardly extending projecting portions enga'geable in an annu- 'lar groove in the rear axle housing and also comprising an adapter surrounding the split bushing and clamping the same upon the rear axle housing. Other objects of the in vention reside in the novel features of construction and combinations and arrangements of parts as will more fully hereinafter appear.

In the drawings:

Figure 1 is a perspective view of a tractor with myinvention applied;

Figure 2 is a plan view thereof;

Figure 3 is a longitudinal sectional elevation of the rear axle housing;

Figure 1 is a cross section on the line 4-4 of Figure 2;

Figure 5 is a cross sect-ion'on the line 55 of Figure 2;

Figure 6 is a front view of the bumper support at the forward end of the engine. The tractor frame comprises the engine 1, the transmission housing 2 and the rear axle housing 3. 4c are the rear drive Wheels at the opposite ends of the rear axle housing. This is a common type of tractor which is not provided with brakes or bumpers as commercially manufactured.

My invention relates to a brake and bumper attachment to a tractor of this type I and as shown the rear wheels 4 have secured to their inner sides brake drums 5, the peripheries of which are engaged by brake bands 6. Actuating mechanism for these brake bands is supported upon the rear axle housing 3 and, as shown, the supporting mechanism comprises the split bushing 7 and the adapter rear axle housing. The split bushing 7 comprises complementary members having inwardly extending projecting portions 9 engageable in an annular groove in the rear the bracket in 8 adjacent each end of the axle housing. The periphery of this split bushing has tapered portions engageable by a correspondingly tapered portion upon the adapter 8 which is drawn longitudinally upon the bushing by the nuts 10 threaded upon the studs 11. The arrangement is such that the split bushing is firmly clamped in place upon the rear axle housing and at the same time the adapter is firmly clamped upon'the bushing. Each adapter is provided with diametrically opposite forwardly and rearwardly extending bosses 12 and 18 respectively, the rearwardly extending bosses being engageable in by the rearwardly extending rods 14 to the rear ends of which is secured the rear bumper 15. 16 is a depending bracket clamped upon each rod 1 adjacent tothe adapter. 17 is a transverse rod journalled in the brackets 16 and having secured to its ends the levers 18 7 which are connected to the brake band actuating levers 19 by means of the intermediate links 20. 21 is a hand lever secured upon the transverse rod '17 for rotating the same co-actuate the brakes. This hand lever is 89 adapted-to be held in adjusted position by means of the dog 22 engageable with the teeth of the segment 23 secured to one of the depending brackets 16.

24 is .the front bumper in advance of the tractor, this bumper being secured to and mounted upon the forward ends of the rods 25, the rear ends of which are mounted in the forwardly extending bosses 12 upon the adapters 8. 26 is a bracket preferably of angle-cross section extending transversely of the engine 1 and mounted upon and secured to the timinggear housing 27. This bracket has outwardly and downwardly extending ends through which the rods 25 pass, these rods being slidably supported by this bracket. intermediate their ends. For securing place one of the cap bolts securing the timing gear housing in place is used. Also. bars 28 are used each having an end secured to an end of the bracket and the other end secured to the under side of the timing gear housing whereby the bracket is held from rocking relative to the ensine. 1

From the above description it will be readily seen that I have provided a simple form of brake and bumper attachment for tractors in which a common support carries the brake actuating mechanism as well as a 1 bumper. It will also be seen that the bumper in advance of the tractor is carried upon rods extending rearwardly to the rear axle housing whereby a stronger and more substantial construction is provided which is more capable of withstanding greater stress than some other part of the tractor, such as the front 1 for example. Still another important consideration resides in the novel and simple construction o1 support comprising a split bushing clamped upon the axle housing and the adapter ecured upon the split bushing.

What I claim as my invention is 1. In a tractor, tue COll'ilJlllZltlUl'l with a lie actu in me .-,nisin1novle relative to said bumper, and a common pport upon suiu tractor for said brake "ng mechanism and bumper.

attachment to a tractor comprising a lmmper, brake actuatii. mechanism morable relative to s ..L bunper and a member secured to said tractor and supporting said bumper and brake actuating mechanism.

3. In a tractor, the combination with the frame including a rear axle housing, of a bumper in advance 01". said tractor, members secured to said rear axle housing near its ends, a member secured to said frame near its forward end, and rods secured to said members upon said rear axle housing and upon said frame near its forward end for carrying said bumper.

l. In a tractor, the combination with the frame including an engine and arear axle housing, of a bumper in advance of said frame, members secured to said rear axle housing near its ends, a member secured to said engine near its .torward end, and rods extending forwardly from said members upon said rear axle housing and supported by said member upon said engine near its forward end, carrying said bumper.

in a tractor. the combination with the frame including an engine and a rear axle housing, ot a bumper in advance of said frame, rods secured to said bumper and extending rearwardly therefrom, supports upon said rear axle housing tor said rods. and a support upon the forward end 01" said engine tor said rods engaging the same intermediate their ends.

6. In a tractor, the combination with the rear axle housing, of biunpers in advance and rear of the tractor, and supports for .gaid bumpers secured to said rear axle housa tractor, the combination with the rear a.:le housing, and drive wheels at the nds thereof, or brake drums upon said drive wheels, brakes engagcable with said drums, actuating mechanism for said brakes, a bumper in rear of the tractor, and corn- 111011 support upon s: .d rear axle housing for said brake actuating mechanism and bumper.

8. in tractor, the combination with the rear a e housing, drive wheels at the ends t er-sot, ot brake drums upon said dre wheels, l 'alies engugeable with said drums, brake iCLU mechanism, adapters, secured upon saic rear axle housing, anal rods carried by said adapters and support ng said brake actuating mechanism.
